Voyager 2 was also to explore Jupiter and Saturn, but on a trajectory that would have the option of continuing on to Uranus and Neptune, or being redirected to Titan as a backup for Voyager 1. Upon successful completion of Voyager 1 's objectives, Voyager 2 would get a mission extension to send the probe on towards Uranus and Neptune. [ 13 ]
The exploration of Uranus has, to date, been through telescopes and a lone probe by NASA's Voyager 2 spacecraft, which made its closest approach to Uranus on January 24, 1986. Voyager 2 discovered 10 moons , studied the planet's cold atmosphere , and examined its ring system , discovering two new rings.
Voyager 2 was the first to be launched. Its trajectory was designed to allow flybys of Jupiter, Saturn, Uranus, and Neptune. Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, [21] which
Voyager 2 visited Uranus in 1986. Much of our understanding of Uranus comes from Voyager 2's flyby, which to date remains the only time a spacecraft has visited the planet.

What’s known about Uranus could be off the mark. An unusual cosmic occurrence during the Voyager 2 spacecraft’s 1986 flyby might have skewed how scientists characterized the ice giant, new ...
[note 2] USA (NASA) ISEE-3/ICE [35] 24 January 1986: First spacecraft to flyby Uranus. USA (NASA) Voyager 2 [38] 19 February 1986: First consistently inhabited long-term research space station. USSR Mir: 13 March 1986: First close up observations of a comet (Halley's Comet, 596 kilometers). ESA Giotto: July 1988
This odd discovery led the Voyager scientists to conclude that the moons must be entirely inactive. But a new analysis of the Voyager 2 data showed that Uranus experienced a rare cosmic occurrence ...
